Answer:The standard deviation on the critical path = 0.834Step-by-step explanation:Variance of activity A () = 0.33

Variance of activity B () = 0.67

Variance of activity C () = 0.33

Variance of activity D () = 0.17

Thus the standard deviation on the critical path () = + + +

= + + +

= 0.6956

= 0.834

The standard deviation on the critical path = 0.834
